This is the first time I’ve had a request for files for 3D printing.
I sent the files as STEP and OBJ and got a response that some walls are missing, the object isn’t closed.
But I’ve checked and used all the analytical tools that Rhino has and I get Rhino Polysurface Object is Valid.
Show Edges shows no naked edges, Select Open Polysurfaces shows no problems.
Can anyone think of anything else I should check?
Thanks in advance.
